The next time you order a pie for yourself and those near and dear to you, don't just toss the box aside. With a few quick steps, you can transform it into four serving plates and a container for your leftovers.

The above video shows the patented "green box" in action, a pizza box specially designed to break down along perforations to give way to cardboard plates and a convenient storage container for the remaining slices. Obviously you can already do the same yourself without too much extra effort, so feel free to apply the idea to your un-perforated pizza boxes. The innovation seems like a handy and environmentally sound way to ditch the paper plates.
